Specification of Letters Patent.

Patented Nov. 1, 1910.

Application led April 7, 1910. Serial No. 554,009.

To all who-m it may concer/n:

Be it known that I, JOSEPH A. TRAMBLEY, a citizen of the United States,residing at Maxbass, in the county of Bottineau and State of NorthDakota, have invented a certain new and useful Improved Wrench; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention has for its object to provide an improved combinationwrench and, to this end, it consists of the novel construction andarrangement of parts hereinafter described and dened in the claims.

The improved wrench is illustrated in the accompanying drawings, whereinlike characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a plan view of the improvedwrench, with some parts shown in section; Fig. 2 is a detail view insection, taken on the line x2 m2 of Fig. 1, on an enlarged scale; andFig. 3 is a detail view partly in section, taken on the line m3 w3 ofFig. 1.

The numeral l indicates a pair of pivotally connected channel-shapedoperating levers having widened anges at one end to form disk-like hubs2. The flanges of these hubs 2 are pressed close together and pivotallyconnected by means of a rivet 3, as best shown in Fig. 3. At their outeredge portions, the hubs 2 are formed with a series of graduatedcooperating wire cutting notches 4.

4Between the internal flanges of the operating levers 1, and justforward of the hubs 2, are rigidly secured a pair of blocks 5, by meansof rivets 6. These blocks 5 have formed on their inner faces a series ofcooperating external thread cutting dies 7 The free outer ends of thelevers 1 are connected by means of a relatively long toggle lever 8 andthe outer ends of the members thereof terminate in laterally projeotingcooperating clamping jaws 9. Each clamping jaw 9 is provided with twosets of teeth 10 and 11, which sets of teeth extend at right angles toeach other, and the teeth 10 extend at right angles to the adjacentmember of the toggle lever 8 and the teeth 1l extend approximatelyparallel therewith.

The outer ends of the die blocks 5 are connected by means of arelatively short toggle lever 12. Axially alined reversely threadedbolts 13 are pivotally connected at their outer ends, one to eachconnection between the members of the toggle levers 8 and 12. The innerends of the bolts 13 have screw-threaded engagement with a comparativelylong nut 14 which acts like a turnbuckle. By turning the nut 14, thetoggle levers 8 and 12 may be buckled more or less and thereby pivotallymove the levers 1 with respect to each other. When the wrench isadjusted to the position indicated in Fig. l, the teeth 10 of the jaws 9are in a position to be clamped onto a comparatively large object, andby rotating the nut 14 still farther to draw the two bolts 13 closertogether, the jaws 9 will be turned into a position so that the teeth 11may be used for clamping comparatively small objects. It is also evidentthat, by rotating the nut 14, the coperating die blocks 5 can beadjusted at will and the hubs 2 moved in respect to each other and usedas a wire cutter.

rIhe tool described will be found serviceable for a great many differentpurposes.

What I claim is 1. In a wrench of the kind described, the combinationwith a pair of pivotally connected operating levers, of a toggle leverconnecting the said pairs of levers, coperating jaws formed on themembers of said toggle lever, and means for moving said toggle lever foropening and closing said jaws, substantially as described.

2. In a Wrench of the kind described, the combination with a pair ofpivotally connected operating levers, of a pair of toggle leversconnecting said operating levers, and the members of one of said togglelevers having a pair of cooperating jaws, a pair of axially alined boltssecured at their outer ends to the pivotal connection between themembers of said toggle levers, and a nut having right and left handthreads for threaded engagement with the inner ends of said bolts,substantially as described.

In testimony whereof I aiix my 4signature in presence of two witnesses.

JOSEPH A. TRAMBLEY.
